Positions (J2000) of the sources at all wavelengths; see text for references. Two black open circles are centred on the position of B1-bS and B1-bN after applying a positional offset correction found by comparing the PACS and Spitzer positions of S295, see text for details. The radius of the circles is the 1σ of the mean of the PACS coordinates, for B1-bS, and of the mean of PACS 100 μm, 160 μm, and SPIRE 250 μm coordinates for B1-bN. The positions at 350 μm, 500 μm, and 850 μm are very uncertain, because B1-bS and B1-bN are not resolved at those wavelengths. The blue open circle centred on Bolo 81 has a radius of 7′′, the pointing accuracy of Bolocam observations (Enoch et al. 2006).
